xpay All Tools

xpay MCP Server

980+ AI tools available as MCP servers. Pay $0.01/call in USDC via the x402 protocol. One API key, 30+ providers — no individual provider accounts or subscriptions needed.

Quick Start

1. Get your API key

Sign up at app.xpay.sh and create an API key. Add credits to your wallet (USDC on Base).

2. Add to your MCP client

Claude Desktop / Cursor / Windsurf — add to your MCP config:

{
  "mcpServers": {
    "xpay": {
      "url": "https://mcp.xpay.sh/mcp?key=YOUR_API_KEY"
    }
  }
}

Claude Code CLI:

claude mcp add --transport http "xpay" "https://mcp.xpay.sh/mcp?key=YOUR_API_KEY"

Replace YOUR_API_KEY with your key from step 1.

3. Use tools

Your AI assistant will automatically discover all available tools. Each tool call costs $0.01 USDC, deducted from your wallet balance.

How It Works

1. Get a key — Sign up at app.xpay.sh and add USDC credits
2. Connect — Add the endpoint URL (with your key) to any MCP client
3. Call tools — Your AI assistant discovers and calls tools naturally
4. Auto-deduct — Each call costs $0.01 USDC, deducted from your wallet balance

No individual provider API keys. No separate accounts. One key for 30+ providers.

Requirements

• API key from app.xpay.sh
• USDC credits in your xpay wallet (add via Coinbase)
• MCP client — Claude Desktop, Cursor, Windsurf, Claude Code CLI, Cline, etc.

How x402 Works

x402 is an open protocol for machine-to-machine payments using HTTP 402 Payment Required. When a tool call requires payment:

1. Server responds with 402 Payment Required + a payment invoice
2. Client signs a USDC payment on Base blockchain
3. Server verifies payment and executes the tool
4. Settlement is instant, non-custodial, and peer-to-peer
